Sets the color depth you'd like AllegroGL to use for video bitmaps.
<p>
This function lets you create video bitmaps of any color depth using allegro's create_video_bitmap(). You can create a RGBA8 bitmap and take advantage of hardware accelerated blending, no matter what the current color depth is. This call will affect all subsequent calls to create_video_bitmap().<p>
Default value for the video bitmap color depth if the color depth of the screen bitmap. To revert to the default color depth, pass -1.<p>
